A Consumerist tipster caught his local Best Buy running a display highlighting the difference between a calibrated and an un-calibrated HDTV. After further examination, the tipster noticed that the un-calibrated TV was hooked up with component cable while the calibrated TV had HDMI. As many of you know, component cable is output at analog, and some devices won't do 1080p without HDMI cables because of copy protection policies. Maybe, in this case, this made a difference in image quality, but generally when you're trying to show side by side benefits of a change, you have to start with the same system in place to avoid causing any doubt to their benefits.
